- 具体要求What the rule requires
- 一般车辆及货物总外宽不得超过 102 英寸，本章另有例外；特定安全装置是否计入测量，须按条文处理。地方政府可在有相应标志的辖区道路限制超过 96 英寸的组合车辆，规划最后一段路线时也须查看这些限制。The general outside width limit for vehicle or load is 102 inches, subject to chapter exceptions and specified safety-device exclusions. Signed local restrictions may prohibit combinations over 96 inches; do not plan the last mile solely from the common national-network width.
(a) (a) The total outside width of any vehicle or its load shall not exceed 102 inches, except as otherwise provided in this chapter.
(b) (b) Notwithstanding any other provision of law, safety devices which the Secretary of Transportation determines to be necessary for the safe and efficient operation of motor vehicles shall not be included in the calculation of width as specified in subdivision (a).
(c) (c) Any city or county may, by ordinance, prohibit a combination of vehicles of a total width in excess of 96 inches upon highways under its jurisdiction. The ordinance shall not be effective until appropriate signs are erected indicating the streets affected.

53 英尺挂车须符合轴距和路线条件Check a 53-foot trailer’s axle placement and authorized route
- 具体要求What the rule requires
- 本条的长度例外仅适用于规定路网，并须满足通达条件。牵引车加一辆半挂车的组合，半挂车通常以 48 英尺为基准；不超过 53 英尺的半挂车，须符合规定的后轴配置，以及 kingpin-to-rearmost-axle 距离条件。53 英尺挂车虽常见，也并非可驶入所有道路。This length exception applies only on the specified network and under its access conditions. For a tractor with a single semitrailer, the baseline is 48 feet; a semitrailer up to 53 feet must satisfy the specified rear-axle configuration and kingpin-to-rearmost-axle distance. Common use of 53-foot trailers does not make every road accessible.
- 条件与例外Conditions and exceptions
- 有两个及以上后轴时，kingpin 到最后轴的距离不得超过 40 英尺；单后轴时不得超过 38 英尺。其他组合及合理通达条件见原文，普通组合长度另见 §35401。With two or more rear axles, the rearmost axle must be no more than 40 feet from the kingpin; with one rear axle, no more than 38 feet. Check the original for other combinations and access; ordinary combination lengths are addressed in §35401.
(a) (a) A combination of vehicles consisting of a truck tractor and semitrailer, or of a truck tractor, semitrailer, and trailer, is not subject to the limitations of Sections 35400 and 35401, when operating on the Dwight D. Eisenhower National System of Interstate and Defense Highways or when using those portions of federal-aid primary system highways that have been qualified by the United States Secretary of Transportation for that use, or when using routes appropriately identified by the Department of Transportation or local authorities as provided in subdivision (c) or (d), if all of the following conditions are met:
(a)(1) (1) The length of the semitrailer in exclusive combination with a truck tractor does not exceed 48 feet. A semitrailer not more than 53 feet in length shall satisfy this requirement when configured with two or more rear axles, the rearmost of which is located 40 feet or less from the kingpin or when configured with a single axle which is located 38 feet or less from the kingpin. For purposes of this paragraph, a motortruck used in combination with a semitrailer, when that combination of vehicles is engaged solely in the transportation of motor vehicles, camper units, or boats, is considered to be a truck tractor.
(a)(2) (2) Neither the length of the semitrailer nor the length of the trailer when simultaneously in combination with a truck tractor exceeds 28 feet 6 inches.
(c) (c) Combinations of vehicles operated pursuant to subdivision (a) may also use highways not specified in subdivision (a) that provide reasonable access to terminals and facilities for purposes limited to fuel, food, lodging, and repair when that access is consistent with the safe operation of the combinations of vehicles and when the facility is within one road mile of identified points of ingress and egress to or from highways specified in subdivision (a) for use by those combinations of vehicles.

单轴载荷和轮胎也有各自限制Check axle and tire loads, not just gross weight
- 具体要求What the rule requires
- 本条一般规定，单轴载荷不得超过 20,000 磅，轴一端车轮承重不得超过 10,500 磅。还须符合轮胎制造商的载荷要求及适用的轮胎宽度限制。双轴或多轴组，应结合轴距，按 §35551 或适用的替代条文确定限重。The general limit in this section is 20,000 pounds per axle and 10,500 pounds on the wheels at one end of an axle, with tire-rating and applicable tire-width limits also relevant. Check tandem or other axle groups separately under §35551 or an applicable alternative using actual spacing.
(a) (a) The gross weight imposed upon the highway by the wheels on any one axle of a vehicle shall not exceed 20,000 pounds and the gross weight upon any one wheel, or wheels, supporting one end of an axle, and resting upon the roadway, shall not exceed 10,500 pounds.
(b) (b) The gross weight limit provided for weight bearing upon any one wheel, or wheels, supporting one end of an axle shall not apply to vehicles the loads of which consist of livestock.
(c) (c) The maximum wheel load is the lesser of the following:
(c)(1) (1) The load limit established by the tire manufacturer, as molded on at least one sidewall of the tire.
(c)(2) (2) A load of 620 pounds per lateral inch of tire width, as determined by the manufacturer’s rated tire width as molded on at least one sidewall of the tire for all axles except the steering axle, in which case paragraph (1) applies.

轴组限重按实际轴距查表Use actual axle spacing for group-weight limits
- 具体要求What the rule requires
- 连续两个及以上车轴的允许重量，取决于轴数及最前轴与最后轴之间的距离，须查阅官方表格和适用例外。地方道路或桥梁可能另有更低限制。条文限值已包含执法容差，不得自行增加所谓“宽限磅数”。Permitted weight for consecutive axle groups depends on axle count and the distance between the outer axles; use the official table and applicable exceptions. Local roads or bridges may impose lower limits. Statutory limits already include enforcement tolerances, so do not add an assumed allowance.
(a) (a) Except as otherwise provided in this section or Section 35551.5, the total gross weight in pounds imposed on the highway by any group of two or more consecutive axles shall not exceed that given for the respective distance in the following table:
Distance in feet between the extremes of any group of 2 or more consecutive axles 2 axles 3 axles 4 axles 5 axles 6 axles 4 34,000 34,000 34,000 34,000 34,000 5 34,000 34,000 34,000 34,000 34,000 6 34,000 34,000 34,000 34,000 34,000 7 34,000 34,000 34,000 34,000 34,000 8 34,000 34,000 34,000 34,000 34,000 9 39,000 42,500 42,500 42,500 42,500 10 40,000 43,500 43,500 43,500 43,500 11 40,000 44,000 44,000 44,000 44,000 12 40,000 45,000 50,000 50,000 50,000 13 40,000 45,500 50,500 50,500 50,500 14 40,000 46,500 51,500 51,500 51,500 15 40,000 47,000 52,000 52,000 52,000 16 40,000 48,000 52,500 52,500 52,500 17 40,000 48,500 53,500 53,500 53,500 18 40,000 49,500 54,000 54,000 54,000 19 40,000 50,000 54,500 54,500 54,500 20 40,000 51,000 55,500 55,500 55,500 21 40,000 51,500 56,000 56,000 56,000 22 40,000 52,500 56,500 56,500 56,500 23 40,000 53,000 57,500 57,500 57,500 24 40,000 54,000 58,000 58,000 58,000 25 40,000 54,500 58,500 58,500 58,500 26 40,000 55,500 59,500 59,500 59,500 27 40,000 56,000 60,000 60,000 60,000 28 40,000 57,000 60,500 60,500 60,500 29 40,000 57,500 61,500 61,500 61,500 30 40,000 58,500 62,000 62,000 62,000 31 40,000 59,000 62,500 62,500 62,500 32 40,000 60,000 63,500 63,500 63,500 33 40,000 60,000 64,000 64,000 64,000 34 40,000 60,000 64,500 64,500 64,500 35 40,000 60,000 65,500 65,500 65,500 36 40,000 60,000 66,000 66,000 66,000 37 40,000 60,000 66,500 66,500 66,500 38 40,000 60,000 67,500 67,500 67,500 39 40,000 60,000 68,000 68,000 68,000 40 40,000 60,000 68,500 70,000 70,000 41 40,000 60,000 69,500 72,000 72,000 42 40,000 60,000 70,000 73,280 73,280 43 40,000 60,000 70,500 73,280 73,280 44 40,000 60,000 71,500 73,280 73,280 45 40,000 60,000 72,000 76,000 80,000 46 40,000 60,000 72,500 76,500 80,000 47 40,000 60,000 73,500 77,500 80,000 48 40,000 60,000 74,000 78,000 80,000 49 40,000 60,000 74,500 78,500 80,000 50 40,000 60,000 75,500 79,000 80,000 51 40,000 60,000 76,000 80,000 80,000 52 40,000 60,000 76,500 80,000 80,000 53 40,000 60,000 77,500 80,000 80,000 54 40,000 60,000 78,000 80,000 80,000 55 40,000 60,000 78,500 80,000 80,000 56 40,000 60,000 79,500 80,000 80,000 57 40,000 60,000 80,000 80,000 80,000 58 40,000 60,000 80,000 80,000 80,000 59 40,000 60,000 80,000 80,000 80,000 60 40,000 60,000 80,000 80,000 80,000
